Round cloth telescopic pipe for ventilation and dust removal and manufacturing method of round cloth telescopic pipe

Abstract

The invention provides a round cloth telescopic pipe for ventilation and dust removal and a manufacturing method of the round cloth telescopic pipe.The manufacturing method comprises the following steps: (1) firstly preparing rectangular main cloth, then preparing a plurality of rectangular cloth strips, wherein the length of the cloth strips is consistent with the length of the main cloth; (2) sewing one side of the long edge of each cloth strip to one side of the long edge of the main cloth, and temporarily not sewing the long edge on the other side; (3) repeating the operation every 15-30 cm; (4) sewing the short edges of the two sides of the main cloth fully provided with the cloth strips to form a sleeve shape needed by the telescopic pipe, wherein the face, provided with the cloth strips in a sewn mode, of the main cloth is located on the outer side of the sleeve; and (5) preparing an annular steel ring, enabling four handles to be evenly distributed on the annular steel ring, forming a hole in the upper end of each handle, sewing the annular steel ring in the cloth strip, then sewing the other side of the long edge of the cloth strip on the other side of the long edge of the main cloth, after the cloth strip is completely sewn with the annular steel ring, enabling a steel wire rope to sequentially penetrate through the handle holes formed in the annular steel ring in the same direction, and completing manufacturing of the telescopic pipe.

Description

technical field [0001] The invention relates to the technical field of environmental protection and dust removal, in particular to a circular fabric telescoping tube for ventilation and dust removal and a preparation method thereof. Background technique [0002] All kinds of mines, cement plants, flour mills, etc., pass through unsealed links with a certain height difference (such as transportation, transshipment, production) during the operation process, causing the raw materials produced to be subject to vibration, collision, etc., which can easily cause various Such dust escapes, causing dust, which has adverse effects on the health of construction workers and poses a threat to people's life and health. Therefore, ventilation and dust removal equipment must be used to control it. Because the ventilation pipe is longer and the diameter of the pipe is larger, especially the ventilation pipe with iron rings fixed, the general sewing method cannot be completed. Contents of ...

[0002] All kinds of mines, cement plants, flour mills, etc., pass through unsealed links with certain height differences (such as transportation, transshipment, production) during operation, which will cause the raw materials produced to be subject to vibrations, collisions, etc., which can easily cause various Such dust escapes, causing dust, which has adverse effects on the health of construction workers and poses a threat to people's life and health. Therefore, ventilation and dust removal equipment must be used to control

Due to the long ventilation pipe and the large diameter of the pipe, especially the ventilation pipe fixed by the iron ring, the general sewing method cannot be completed
